It's not about the grasp, it's about the location.So I am just too limp wristed for it to sense I have my hand on the wheel. Guess I have to work on a heavier grasp.
If you keep your hand on the bottom, you're not really torquing the wheel.
I keep it on the left side, almost no grasp and let it rest. The weight of my hand is enough to trigger the torque sensor.
